Proposal

Occultation of TYC 1236-00841-1 by Titania on 2023 November 21 for BSM-NH2.

Hello!

On November 21, 2023, a rare event will occur - occultation of bright R = 11.75 star by Uranus' satellite Titania (maximum duration = 72.8 sec.). This is an important phenomenon for science (as written here https://groups.io/g/IOTAoccultations/topic/forthcoming_stellar/102356665 ) and the imaging technique is similar to imaging of eclipses of binaries, so I think that such a proposal for the AAVSOnet is appropriate.

Only one telescope is within the area of ​​visibility: BSM-NH2. Event Mid-Time: 05:16:55 UT for this location, accordingly, I request continuous shooting starting 60 minutes before and 60 minutes after (to measure the separated flux from Titania and the star both before and after the occultation) with Rc filter: from 04:15 to 06:15 UT.

The shutter speeds are necessary so that the SNR is not too low for 14-mag Titania during the occultation and so that there is no illumination of the Titania position from Uranus, so this needs to be checked in advance: will it be 1 second or 0.1 second.

With best regards, Filipp Romanov.

The purpose of observing this event is admirable, but does not align the purpose of AAVSO which is variable stars an exoplanets, not planetary science. I know there will be a lot of attention paid to this by others and I myself have been making observations of Titania in the last few weeks to nail down the astrometry.

Thank you for your reply, I understood it. I successfully observed this occultation using other remote telescopes: https://spaceweathergallery2.com/indiv_upload.php?upload_id=202014
